3.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Al Viro <[email protected]> commit 60bb45297f7551833346c5cebc6d483ea17ea5f2 upstream. If DIO results in short write and sync write fails, we want to bugger off whether the DIO part has written anything or not; the logics on the return will take care of the right return value.
